2021-03-02perf vendor events power9: Remove unsupported metricsPaul A. Clarke1-132/+0
Several metrics are defined based on unsupported / non-existent events, and silently discarded. Remove them for good code hygiene and to avoid confusion. Signed-off-by: Paul A.

2020-08-14perf stat: Update POWER9 metrics to utilize other metricsPaul A. Clarke1-24/+24
These changes take advantage of the new capability added in merge commit 00e4db51259a5f936fec1424b884f029479d3981 "Allow using computed metrics in calculating other metrics". The net is a simplification of the expressions for a handful of metrics, but no functional change.
